Docker configuration Alibaba Cloud image acceleration pull implementation

Today I used docker to pull the image, but the speed was so bad that I couldn't see it, and I kept waiting until the end.

read tcp 192.168.31.60:55550->104.18.123.25:443: read: connection reset by peer

Transmission anomaly

Then I saw on the Internet that I could configure the image acceleration provided by Alibaba Cloud

Specific method

Enter Alibaba Cloud's Container Image Service

Quick Links: Container Registry

Copy the accelerator address

Find the daemon.json file in the /etc/docker directory (create it if it doesn’t exist) and write the following content into it

  {
   "registry-mirrors": ["https://xxxxxx.mirror.aliyuncs.com"]
  }

The address is the address you copied on the Alibaba Cloud website in step 2

Restart daemon

systemctl daemon-reload

Restart the Docker service

systemctl restart docker

Done, tested it, the pull is fast and comfortable. . . .

Additional knowledge: Docker pull/push images from Alibaba Cloud

Log in to Alibaba Cloud Docker registry:

$ sudo docker login [email protected] registry.cn-hangzhou.aliyuncs.com

The username for logging into the registry is the full name of your Alibaba Cloud account, and the password is the password you set when activating the service.

You can change the docker login password by clicking the button in the upper right corner on the image management homepage.

Pull the image from the registry:

$ sudo docker pull registry.cn-hangzhou.aliyuncs.com/qz/nginx-vim:[image version number]

Push the image to the registry:

$ sudo docker login [email protected] registry.cn-hangzhou.aliyuncs.com

$ sudo docker tag [ImageId] registry.cn-hangzhou.aliyuncs.com/qz/nginx-vim:[image version number]

$ sudo docker push registry.cn-hangzhou.aliyuncs.com/qz/nginx-vim:[image version number]

Please fill in [ImageId] and [Image version number] according to your own image information.

Pay attention to your network environment

When pushing images from ECS, you can choose to use the intranet, which will greatly increase the speed and will not consume your public network traffic.

If the machine you applied for is in the classic network, please use registry-internal.cn-hangzhou.aliyuncs.com as the domain name of the registry to log in and as the image namespace prefix

If the machine you applied for is in a vpc network, please use registry-vpc.cn-hangzhou.aliyuncs.com as the domain name of the registry to log in and as the image namespace prefix

sample:

Rename the image using docker tag and push it to the registry via the private network ip:

$ sudo docker images

REPOSITORY TAG IMAGE ID CREATED VIRTUAL SIZE
registry.aliyuncs.com/acs/agent 0.7-dfb6816 37bb9c63c8b2 7 days ago 37.89 MB

$ sudo docker tag 37bb9c63c8b2 registry..aliyuncs.com/acs/agent:0.7-dfb6816

Find your imageId through docker images and rename the image domain to the registry intranet address for the changed imageId.

$ sudo docker push registry..aliyuncs.com/acs/agent

The above article about configuring Alibaba Cloud image acceleration pull in Docker is all I have to share with you. I hope it can be a reference for you. I also hope that you will support 123WORDPRESS.COM.
